Here, the sensing paddle 62 is a paddle body 62-2 coupled to the paddle shaft portion 62-1 and a paddle body along the outer circumferential surface of the paddle body 62-2 corresponding to the unit discharge groove portion 22. (62-2) may include sensing blades 62-3 disposed at equal intervals. Then, the speed sensor 63 can detect the amount of rotation of the distribution module by sensing the sensing blades 62-3.

In the sensing paddle 62, one of the paddle body 62-2 or the sensing wing 62-3 is provided with a default setting unit 62-4 to discharge unit from the inlet 11 of the metering housing 10. It is possible to keep the groove part 22 in a stable open state, and it is possible to promote initialization of the distribution module 20 .

The rotation sensing module 60 includes a sensing body 61 coupled to the conversion module 40 or the shaft coupling module 30 or the metering housing 10 so that some or all of the sensing paddle 62 and the speed sensor are embedded. can include more.

Referring to the first coupled state, as shown in FIG. 14 , the sensing blades 62-3 may be bent from the edge of the paddle body 62-2. And the speed sensor 63 is spaced apart from the outside of the imaginary cylinder connecting the sensing wings 62-3 and coupled to the sensing body 61. Then, since the speed sensor 63 is spaced apart from the paddle body 62-2 and is disposed to face only the sensing blades 62-3, the sensing blades 62-3 are moved according to the rotation of the paddle shaft portion 62-1. Can be detected intermittently. Since the width of the sensing blades 62-3 corresponding to the rotational direction of the paddle shaft portion 62-1 forms the preset first sensing width, the unit discharge groove 22 corresponds to the inlet 11 or the outlet 12. ), and when the rotational force of the distribution module 20 is controlled by the speed control module 70, a predetermined amount of powder is stably accommodated in the unit discharge groove 22.

Referring to the second coupled state, as shown in FIGS. 15 and 16 , the sensing blades 62-3 may protrude from the circumferential surface of the paddle body 62-2 in a normal direction. And the speed sensor 63 is spaced apart from the outside of the imaginary cylinder connecting the sensing wings 62-3 and coupled to the sensing body 61. Then, since the speed sensor 63 is arranged to look at both the circumferential surface of the paddle body 62-2 and the sensing blades 62-3, the sensing blades 62-3 are rotated according to the rotation of the paddle shaft portion 62-1. ) can be detected intermittently. Since the width of the sensing blades 62-3 corresponding to the rotational direction of the paddle shaft portion 62-1 forms a second sensing width smaller than the preset first sensing width, it corresponds to the inlet 11 or the outlet 12. to clarify the location of the unit discharge groove 22, and when the rotational force of the distribution module 20 is controlled by the speed control module 70, a predetermined amount of powder is stably in the unit discharge groove 22 make it acceptable

Referring to the third coupled state, as shown in FIG. 17 , the sensing blades 62-3 may protrude from the circumferential surface of the paddle body 62-2 in a normal direction. And the speed sensor 63 is coupled to the sensing body 61 so as to face the side of the paddle body 62-2. Then, since the speed sensor 63 is arranged to look only at the sensing blades 62-3 in a direction parallel to the paddle shaft portion 62-1, the sensing blades 62-3 are rotated according to the rotation of the paddle shaft portion 62-1. ) can be detected intermittently. Since the width of the sensing blades 62-3 corresponding to the rotational direction of the paddle shaft portion 62-1 forms the preset first sensing width, the unit discharge groove 22 corresponds to the inlet 11 or the outlet 12. ), and when the rotational force of the distribution module 20 is controlled by the speed control module 70, a predetermined amount of powder is stably accommodated in the unit discharge groove 22.

Referring to the detailed coupling relationship of the rotation sensing module 60, the width of the sensing blades 62-3 corresponding to the rotation direction of the paddle shaft portion 62-1 and the distance between the two adjacent sensing blades 62-3 It is possible to adjust the time for the speed sensor 63 to detect the sensing blades 62-3, the time for adjusting the rotational force generated in the power generation module 50, etc., and accommodated in the unit distribution groove 22 The powder can be clearly controlled.

The speed control module 70 adjusts the rotational force generated in the power generation module 50 according to the position of the unit discharge groove 22 of the distribution module 20 detected by the rotation sensing module 60. The control method of rotational force in the speed control module 70 can be divided into a fine deceleration method and an accommodating acceleration method. Then, the position of the unit discharge groove ( ) is detected through the rotation sensing module 60, and the weight value of the powder accumulated in the unit discharge groove 22 is calculated according to the control of the speed control module 70, and the unit discharge By converting the weight of the powder per groove 22, it is possible to minimize the error value according to precise measurement.

According to the fine deceleration method, the speed control module 70 includes a detection confirmation unit 71 that checks whether a detection signal is generated in response to the amount of rotation of the distribution module 20, and detects the check result of the detection confirmation unit 71. If the signal is not generated, the acceptance control unit 72 that maintains the rotational force generated in the power generation module 50 and the detection confirmation unit 71 check the detection signal to generate the rotational force generated in the power generation module 50. It may include an adjustment control unit 73 that reduces the deceleration force to a predetermined level.

According to the acceptance acceleration method, the speed control module 70 includes a detection confirmation unit 71 that checks whether a detection signal is generated in response to the amount of rotation of the distribution module 20, and detects the check result of the detection confirmation unit 71. When a signal is generated, the acceptance control unit 72 that maintains the rotational force generated from the power generation module 50 and the detection confirmation unit 71 check that if the detection signal is not generated, the rotational force generated from the power generation module 50 is checked. It may include an adjustment control unit 73 that increases the acceleration to a predetermined acceleration.

For example, while the speed sensor 63 detects the sensing blades 62-3 of the sensing paddle 62, the speed control module 70 relatively reduces the rotational force of the power generation module 50 and Since the distribution module 20 rotates slowly, the communication time of the unit discharge groove 22 at the inlet 11 is relatively long, and 85% to 90% of the unit discharge groove 22 at the inlet 11 It is possible to maintain the communication state so that the powder is sufficiently supplied to the unit discharge groove 22. In addition, when the speed sensor 63 does not detect the sensing blades 62-3 of the sensing paddle 62, the speed control module 70 relatively increases the rotational force of the power generation module 50 and Since the distribution module 20 rotates quickly, the communication time of the unit discharge groove 22 at the inlet 11 is relatively shortened, and a portion of the powder delivered from the hopper (of the powder accommodated per unit discharge groove 22) 10% to 15%) can be supplied to the unit discharge groove (22).

As another example, while the speed sensor 63 detects the sensing blades 62-3 of the sensing paddle 62, the speed control module 70 relatively reduces the rotational force of the power generation module 50 and Since the distribution module 20 rotates slowly, powder can be delivered to each of the two adjacent unit discharge grooves 22. In addition, when the speed sensor 63 does not detect the sensing blades 62-3 of the sensing paddle 62, the speed control module 70 relatively increases the rotational force of the power generation module 50 and Since the distribution module 20 rotates quickly, the communication time of the unit discharge groove 22 at the inlet 11 is relatively short, and one of the two adjacent unit discharge grooves 22 moves quickly to the outlet 12. And, the other one of the two adjacent unit discharge grooves 22 increases the communication area with the inlet 11, but part of the powder delivered from the hopper (10% to 15% of the powder accommodated per unit discharge groove 22) Only can be supplied to the unit discharge groove (22).
